1) Propose distinguishing between two types of heliocentrism -- the center of the universe and the center of the solar system.  We're conflating two uses of the term here, and that causes confusion.

2) Propose clarifying that while systems can legitimately be described in any reference frame, ''inertial'' reference frames are privileged, because they don't require the introduction of fictitious forces.  Thus, you can describe the universe as centered on an immobile Earth, but that requires you to introduce all sorts of fictitious forces to explain why the enormously massive sun inexplicably curves around us.  the solar system is ''better'' and ''more simply'' described as centered on the sun.  [[User:Ungtss|Ungtss]] 15:44, 27 September 2008 (EDT)
